So thoughts on the planes:
Venom -its a Spitfire Ia without the speed/altitude or style. Its OK
P-40 M-105 -aesthetics of the P-40 wrecked by the smaller spinner & flatspot, not quite got the speed of the classic P-40, lacks altitude performance but gains some rockets, not sure if they are all that useful, pretty good plane.
Tomahawk IIb -older model P-40, 2* 12.7mm, 4* 7.62mm so a bit weak firepower wise but despite the weaker engine horsepower it feels more like tech tree P-40 to fly.
Airabonita -probably everyone already has it and I think best of the bunch. Is a good TnB with the 37mm for solid firepower when you get your aim in.
Me 209 v4 -looks like a great big silver turd, flies like one too. Its fast with good altitude but thats it, turns like a Heavy and has weak firepower to boot.
